Difficultes in determination of elements through the ICP-MS techniques for plant materials with different silicon content

Abstract

After determination of Si concentrations plant reference materials were digested in (HNO3+H2O2, HNO3+H2O2+HF+H3BO3 and in HNO3+H2O2+HBF4). 36 elements were determined by IFCP-MS technique. Si content in plant specimens significantly influences determinat
